Five models of dedicated glycol chiller — 2,750 BTU to 12,900 BTU — sized for everything from a single jacketed Unitank to a 10 BBL production fermentation hall. Same architecture across the line: sealed refrigeration compressor, copper-tube evaporator, food-safe propylene glycol loop, and from BEF-05 up the integrated Chiller Watch remote monitoring. Picked correctly, one of these holds your lager at 33°F through a 6-week cold conditioning without breathing hard.
The MCED line is purpose-built for brewing. That means the compressor is sized for sustained pull-down (not a 5-minute commercial freezer duty cycle), the reservoir is set up for food-safe propylene glycol, and the pump ports scale from a single homebrew fermenter all the way to a 12-loop production cellar when paired with the BFT-67 buffer tank.
The same class of sealed, oil-charged compressor that runs commercial display fridges and walk-ins — quiet, refrigeration-grade, spec'd for sustained pull-down. Sized with headroom above advertised load so it isn't running flat-out during a lager crash.
Refrigerant chills the inside of a copper coil; the coil sits inside a reservoir of food-safe propylene glycol. Big thermal mass means short compressor cycles — the reservoir absorbs demand spikes when two fermenters call for cold at the same time, so the compressor isn't chasing the load in real time.
Integrated on BEF-05 and BEF-075, add-on for BEF-100 and BEF-150. WiFi-connected — check system temperature, glycol pressure, and status from your phone, with alerts if the loop goes out of range. The on-unit thermostat handles the reservoir set point separately (mechanical on BEF-02; digital on BEF-05 up).
Every MCED chiller ships with 3/8" barb supply and return ports — universal, non-proprietary, adapts to anything. For our jacketed Unitanks, the Temperature Control Kit steps 3/8" barb up to tri-clamp, and our 5' TC line set completes the loop to the fermenter jacket. Drop-in for every Bräu Supply Unitank; adapts to any commercial fermenter with a standard glycol jacket.
A glycol chiller is just a cold reservoir with a pump. It doesn't care whose name is on the fermenter jacket — if you've got 1/2" NPT ports and a solenoid valve, you've got cold beer. Common pairings on the Bräu Supply side:
Pick by the BTU/hr load your fermentation hall actually pulls — not by ambition. Undersize and you'll grind the compressor through lager crashes; oversize by more than a notch and you'll short-cycle the loop. Most homebrewers want a BEF-02. Most pilot operations want a -05 or -075. Production runs -100 or -150.
The benchtop chiller — sized for one to two jacketed homebrew Unitanks under ale duty. Mechanical thermostat on-unit; pair with our SV1 controller for digital set-point logic at the fermenter.
The two chillers that ship with integrated Chiller Watch remote monitoring — see system temperature, glycol pressure, and status from your phone. Sized for a 3 BBL nano up through a 5 BBL pilot with multiple parallel fermenters cold-crashing simultaneously. BEF-05 (most-selected) for 3-5 BBL pilot; BEF-075 stretches to 5-7 BBL with up to 3 built-in circulation pumps.
Commercial-duty chillers for 5–15 BBL fermentation halls. 220V single phase, 17-gal reservoir standard, Chiller Watch remote monitoring available as an add-on. Routinely paired with our BFT-67 buffer tank for breweries running four or more fermenters in parallel — the BFT-67 scales the loop to 12 pumps and 67 gallons of thermal mass.
A fermentation cold-crash is a 24-hour event, not a five-minute spike. MCED compressors are spec'd with headroom above advertised load — the unit lives with margin instead of running flat-out and burning bearings.
Every reservoir is set up for food-grade propylene glycol — never the ethylene glycol you'd put in a car. A leak in the jacket loop won't contaminate a batch. Pre-mixed glycol available at checkout for first fill.
WiFi remote monitoring — system temperature, glycol pressure, status, alerts — visible from your phone. Integrated on BEF-05 and BEF-075; available as an add-on for the BEF-100 and BEF-150. On-unit thermostat handles the reservoir set point separately.
Chiller ports are plain 3/8" barb — the universal glycol fitting. Our Temperature Control Kit adapts 3/8" barb → tri-clamp, and the matching 5' TC line set closes the loop to a Bräu Supply jacketed Unitank. Plug-and-play from box to fermenter.
The reservoir buffers the chiller against demand spikes. On the 17-gal models (BEF-05 up) you can spec up to 4 circulation pumps standard, 6 custom — one per fermenter loop. Add the BFT-67 buffer tank for production halls: 67 gallons of thermal mass, up to 12 pumps.
Sealed compressors, copper coils, and standard solenoids — all serviceable. We stock spares for every model and walk owners through field repairs over a video call. The chiller you buy in 2026 is the chiller you're still running in 2036.
Quick rule of thumb: 1,500–2,000 BTU/hr per active jacketed BBL under cold crash. Round up one notch if you're cold-crashing two tanks in parallel. Round up two notches if you're in a hot ambient or running ferments below 35°F.

Outgrowing your chiller is a real outcome — fermentation halls scale faster than chillers. Plan for the next size up by leaving headroom on plumbing and reservoir, and the upgrade path is bolt-in.

Use the rule of thumb: 1,500–2,000 BTU/hr per active jacketed BBL under cold crash. A 1 BBL fermenter wants ~2,000 BTU; a 5 BBL hall with two parallel ferments wants ~10,000 BTU; a 10 BBL hall wants 12,900+ BTU. Round up if your brewery runs hot, if you cold-crash multiple tanks simultaneously, or if you regularly hold lager temps below 35°F. Send us your fermenter list and we'll size it for you.
Propylene glycol is the food-grade glycol approved for indirect food contact. Ethylene glycol (automotive antifreeze) is toxic. A leak in the jacket loop on propylene means you toss the batch out of an abundance of caution; a leak with ethylene means you've contaminated the brewery. Every MCED chiller reservoir is rated for propylene only — we sell pre-mixed glycol at checkout for first fill.
WiFi remote monitoring — see system temperature, glycol pressure, and status from your phone, plus fault alerts if the loop goes out of range. Integrated on BEF-05 and BEF-075; available as an add-on for the BEF-100 and BEF-150. On-unit temperature set-point is handled by a separate thermostat (mechanical on BEF-02, digital on BEF-05 up). It's a monitoring layer, not a replacement for the fermenter-side temp controller.
Not for homebrew or single-fermenter pilot ops — the chiller's internal reservoir is enough. For production halls running four or more fermenters in parallel, a BFT-67 buffer tank adds 67 gallons of thermal mass and lets a smaller chiller punch above its weight. Most often paired with the -075, -100, and -150.
Sealed refrigeration compressors are quiet — comparable to a household refrigerator at idle, roughly 52–58 dB at 3 ft. Loud enough that you don't want one inside a tap room while pours are happening, but quiet enough for a basement brewery, a back-of-house storage room, or an outdoor enclosure.
No. Every price on this site includes free continental US shipping, and we prepay all duties, tariffs, and brokerage on your behalf. You won't get a courier collect-on-delivery for $400 of surprise import fees three days after your chiller lands. The price you see is what you pay. (Alaska, Hawaii, and international freight — contact us for a quote.)
1-year full warranty on the compressor, controller, pump, and refrigeration loop. Lifetime parts & refrigeration support — every component is individually replaceable, and we walk owners through field repairs over video. The architecture is designed to be serviced, not replaced.
Yes — every MCED chiller has 3/8" barb supply and return ports, the universal glycol fitting. For our jacketed Unitanks, the Temperature Control Kit adapts 3/8" barb → tri-clamp and the 5' TC line set completes the loop. For a fermenter you already own, connect 3/8" ID silicone or braided line to the chiller and terminate however your jacket is set up. Add a temperature controller + solenoid valve at the fermenter end and you've got closed-loop temp control. Most retrofit setups are running the same week the chiller arrives.
Pick the BTU that matches your fermentation load — the architecture, the plumbing, and the controller stay constant when you grow.
